little bug + new feature (alternate chords play)

Dear developers,

Your app is GREAT! Thanks a lot. I'm using it every day for practising.
I'd like to mention a bug and a feature request:

- since the upgrade to ics on my samsung galaxy 10.1 often after playing a chorus, irealb freezes for 1 second and continues playing problemless aftewards. This has never been the case on honeycomb.
- would this global setting be a possibility in a future version: 'In middle chorus(ses) play alternate chords' ?

Many thanks,
daLooney
